Seeing as it's a tie, I thought I would post.
I went with The Warriors in this one. It was only recently that I actually watched The Warriors, because previously I didn't think I would like it, but after watching it; I thought bad of myself for leaving it this long. Basically it's awesome, well for the most part anyway. When it sticks to the white-knuckle suspense and excellent fight scenes and ever increasing tension, the film excels. The dialogue in the film isn't great and neither is the script, but I still really enjoyed the film and for once, a cult film that actually deserves its praise.
Little Miss Sunshine on the other hand never really interested me. Not to take anything away from the film but, I was bored by it during my viewing of it. The acting is very good though with Steve Carell and Alan Arkin delivering the best performances. A fine film, but not my cup of tea.
